Let me first describe what either is.
A dozen human is someone who goes with the flow, this type of person walks on a well stepped on path. They rarely go on themselves and are rather social beings. They thrive in company often they are joiners and join a activity just for the company of other humans.
They "swallow" everything they get taught, rarely they think and criticize therefore they can easily follow dictators and similar. This can make them rather dangerous.
Rarely they think of themselves as to what I described above, yet for the majority of them this holds true.
Many religions host this kind of people, they take their book as sacred but few have read other "holy books" out of i.e. curiosity. Many are simple minded and hard to discuss (argue?) with.
The main thing of importance is that they never criticize what they get taught and they think in lines. (simple minded)
So what do I mean by a "free" human?
They are free of any limitations of mind, often they enjoy to ponder and even criticize things.
They are not afraid to walk alone, some even enjoy the peace of being alone.
I find them often to philosophise about a large variation of things.
Being free in their mind can make them rather unpopular with some people.

Where do you fit?
Note! Of course this is a rather big generalization, there are many other factors that could be included. I just try to keep this simple so everyone can follow.
I hope you find what you seek,
